Aquaseal Basement Waterproofing Contracting Ontario

I had a damaging basement water leak at a rental property and called Pierre at Aquaseal. I was desperate to get the situation assessed. Pierre told me he would come to my rental property but would charge me $395.00 to assess the situation which would be taken off the total repair costs if I used Aquaseal. I stupidly agreed to pay because I was desperate and wanted to assess the cause of the problem. Pierre came to my rental property the following morning at approximately 7:30am and spent no more than 5 to 10 minutes (I was not home at the time - the tenents informed me of this). I had to phone Pierre two days following his visit to the rental property (he didn't call me) and he provided his opinion over the phone. I asked for an invoice and writen assessment of the cause and Pierre simply sent me a price list from his website. I appreciated that Pierre did not want to provide an estimate or opinion that didn't lead to future work however, I feel the 395.00 was not reasonable for what he did (a quick 5-10 minute assessment at the home and a phone call). Pierre recommended I hire a plumber to assess if the main drain was blocked so I followed his recommendation - the plumber found no issues and charged me another $300.00. The issue I have is that I had two other water leak repair companies come to the home and both charged $0 for the assessment/estimate and both provided a detailed quote in writing. It is interesting that the other two water leak repair companies provided a differentiate assessment to the cause of the leak. I am not saying Pierre's assessment was incorrect, but I am saying that the assessments these companies make are somewhat of a art and to charge 395.00 for an assessment and estimate is not reasonable and simply predatory to take advantage of people when they are in a desperate situation. I did write to Aquaseal to ask for a refund of $250.00 (hence paying Pierre $150 for his assessment of the home and phone call to me) because I felt his charge was excessive. I did not get a reply to my written request for refund.
